          In this variant, in one of the source files, you now have to define your

          runner</a> <code class="computeroutput"><span class="identifier">unit_test_main</span></code>

          function</a> <code class="computeroutput"><span class="identifier">init_unit_test</span></code>
          as argument. You need to define <a class="link" href="../../utf_reference/link_references/link_boost_test_no_main.html" title="BOOST_TEST_NO_MAIN"><code class="computeroutput"><span class="identifier">BOOST_TEST_NO_MAIN</span></code></a> (its value
